The Sun shows some signs of life
Earlier this week NOAA’s Space Weather Prediction Center published its monthly update of the Sun’s sunspot cycle. As I do every month, I’ve posted the newest graph below, showing the continuing slow rise in sunspots (blue/black lines) in comparison with the consensis prediction made by the solar science community in May 2009 (red line).
In February the sunspot count finally recovered from its wimpy showing in December. In addition, the sun has been quite active in recent weeks, more active than it has been in years. What this means, however, for the upcoming solar maximum remains unclear, though it still seems likely that the next maximum will be the weakest in more than 200 years (see the graph on this page). The newest prediction for the next solar maximum, from solar scientists at the Marshall Space Flight Center, also predicts this, and the sunspot numbers we are seeing are still in line with that new prediction.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
It looks like to stay on track with their current prediction, the solar scientists at the Marshall Space Flight Center, are predicting a large spike in sunspot activity very soon.
